When those of us who grew up with the original
Star Wars trilogy thought of what might happen in the long-awaited prequels, I strongly suspect most of us expected something a bit more like
Rogue One (2016). We'd only received glimpses of the pre-Luke Skywalker past, embedded in the story we'd heard about the Clone Wars, an Anakin Skywalker who was supposed to be some sort of edgy fighter pilot who becomes a Jedi... I was expecting three movies that took place against the backdrop of The Clone Wars, which always sounded pretty rough, at least in my head.
I'd also observe - Much as the superhero comics we read grew up with us, I think maybe I was expecting a Star Wars that acknowledged the conflict from which
Episode IV sprang and maybe cut a little deeper - maybe had a bit of a rough and tumble edge that Ewok-laden finales may have foregone.
So, I think it's true that the content and execution of the three Prequel films surprised a lot of us.
Rogue One, the second of these films directed by the generation that grew up on them, expands upon what we know, creating far less continuity difficulty than Lucas introduced in the Prequels, brings back familiar sights and sounds, while filling in gaps and giving us all new adventures and characters. In this, I think you can say it succeeds with a solid A-, B+ (I spotted an issue or two, and my pal Matt brought one up I thought actually a pretty salient point).
That's not to say
Rogue One hits all the right notes or was exactly what I was expecting (it wasn't). It's interesting to see Disney seeking to expand upon the seemingly vast universe Star Wars always promised, but which we could only visit in 150 minute increments. Here, they risk tonal differences, deliver only bits of familiar characters and try something a little uncomfortable, and, for the most part, they succeed.
